Contoh
Contoh berikut membuat instans XmlRootAttribute dan menetapkannya ke XmlRoot properti XmlAttributes objek.
XmlSerializer Saat menserialisasikan MyClass
objek, objek menggunakan XmlRootAttribute objek untuk mengambil alih elemen akar default.
#using <System.Xml.dll>
#using <System.dll>
using namespace System;

using namespace System::Xml::Serialization;
// This is the class that is the default root element.
